Chapter 6 Monitor FQDN can be used in Security Policy, Policy Route, BWM and Web Authentication profiles as source and destination criteria. FQDN with a wildcard (for example, *.zyxel.com) can be used in these profiles as destination criteria only. Suppose you want to block certain users from going to a website with a dynamically updated IP address using DDNS. Create an FQDN object for the website in Object > Address, and then create a Security Policy in Security Policy > Policy Control > Add. Use the FQDN object to identify the website as a destination, and configure specific users to block. When a user tries to connect to the forbidden website, the Zyxel Device first checks the IP address - website mapping in response to the DNS query and then finds the FQDN object match. The Security Policy that has this FQDN object match can then block the configured users from accessing the website. Figure 132 Monitor > System Status > FQDN Object The following table describes the fields on the previous screen. Table 45 Monitor > System Status > FQDN Object LABEL DESCRIPTION IPv4 FQDN Object Cache List You must first configure IPv4 FQDN objects in Configuration > Object > Address/Geo IP in the IPv4 Address Configuration field. FQDN Object Select a previously created object from the drop-down list box to display related FQDN object caches used in DNS queries. # This is the index number of the FQDN entry. Name This field displays the name of the selected FQDN object used in DNS queries. FQDN This field displays a host's fully qualified domain name. IP Address This field displays the mapping of the FQDN to an IP address. This is the IP address of a host. TTL This field displays the number of seconds the Zyxel Device holds IP address - FQDN object mapping in its cache. The mapping is updated when the TTL (Time To Live) setting expires. IPv6 FQDN Object Cache List You must first configure IPv6 FQDN objects in Configuration > Object > Address/Geo IP in the IPv6 Address Configuration field. ZyWALL ATP Series User's Guide 153
